      blk-mq: make per-sw-queue bio merge as default .bio_merge · 9bddeb2a
      Ming Lei authored
      Because what the per-sw-queue bio merge does is basically same with
      scheduler's .bio_merge(), this patch makes per-sw-queue bio merge
      as the default .bio_merge if no scheduler is used or io scheduler
      doesn't provide .bio_merge().

      blk-mq: merge bio into sw queue before plugging · ab42f35d
      Ming Lei authored
      Before blk-mq is introduced, I/O is merged to elevator
      before being putted into plug queue, but blk-mq changed the
      order and makes merging to sw queue basically impossible.
      Then it is observed that throughput of sequential I/O is degraded
      about 10%~20% on virtio-blk in the test[1] if mq-deadline isn't used.
      
      This patch moves the bio merging per sw queue before plugging,
      like what blk_queue_bio() does, and the performance regression is
      fixed under this situation.
      
      [1]. test script:
      sudo fio --direct=1 --size=128G --bsrange=4k-4k --runtime=40 --numjobs=16 --ioengine=libaio --iodepth=64 --group_reporting=1 --filename=/dev/vdb --name=virtio_blk-test-$RW --rw=$RW --output-format=json

      The code in blk-mq-debugfs.c assumes that it is working on a blk-mq
